Part Inspection in Batches

By | 2018-01-12T08:29:32+00:00 December 20th, 2017|Categories: 3D Scanning|0 Comments

You can easily perform part inspections in batches and automatically generate inspection reports for each part using a Creaform HandyScan scanner, along with Geomagic Control X software. The first step is to capture your parts’ geometry with a metrology grade, certified scanner. Scan each part in the batch, and export an STL file. It’s handy to put all of the scans in one folder. The next step involves creating a master file that will be used for comparison and inspection. Once you’ve imported the CAD file into Control X, add the appropriate dimensions, tolerances, Datums, and GD&T information to the CAD model. This critical inspection information may also be seamlessly transferred from CAD into Control X. Next, choose the method of alignment for your scan, so that you can align it with the CAD model correctly. Although we typically use the datums called out on the manufacturing drawing, various alignment methods are available depending on the need. Once you have the scan aligned, create the types of analysis that will be performed and orient their corresponding views. Last, you can prepare your report by choosing which information you want to include. You will notice that with little effort, the analysis [...]

Reverse Engineering a BMW Speaker

By | 2017-12-19T09:21:32+00:00 December 6th, 2017|Categories: 3D Printing / Additive Mfg, 3D Scanning|0 Comments

Reverse Engineering has many purposes, one of them being to recreate parts or components that are no longer manufactured. With straight-forward mechanical components, this can be accomplished with a variety of measuring instruments. This task can quickly become more complex though, if the part takes on more of a freeform or ergonomic shape. To serve as an example, the president of our company recently had one of his speaker covers broken. Despite the fact that this is something that can be purchased, we decided to reverse engineer it with all the available tools here at Cimquest. The first step was to scan the part and capture as much as the geometry as possible. This was done with the Creaform HandyScan 700 scanner, which has a resolution of .2 millimeters. Next, we imported the scan into Geomagic Design X. This software allows us to interrogate our scan, and trace the outline of each feature that we need in order to recreate our CAD file. When we’re done, we end up with a fully-featured, editable CAD file that can be exported into a variety of CAD packages. In CAD, you are able leverage these fully editable features to make modifications and optimize [...]

Reverse Engineering a 3D Pipe

By | 2017-12-21T09:14:21+00:00 September 20th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

This blog article will illustrate how to extract the centerline of a 3D pipe with compound angles. Extracting the centerline of a 3D pipe that contains angles in 2 dimensions is not that complicated. However, when you have compound angles, and the tube is bending in the X, Y, and Z directions simultaneously, extracting the centerline can be quite challenging. For example, below we have a prototype of ½ of a bicycle handle, printed on the HP Printer, in Nylon 12. It contains bends in compound angles. Let’s say you don’t have the CAD file to work with and would like to extract the centerline, so that you can create a true CAD file, improve it, and then eventually create a manufacturing drawing . . . One solution to accomplish this is to use Geomagic Design X software and this is how it would work. First, you would need to capture the physical geometry of the handle bar using a 3D scanner and then export an STL file. Next, import the STL file into Geomagic Design X. Design X has a function called: Sweep Wizard. With a few clicks, it produces a fully editable feature tree to create this shape. [...]

CMM Inspection without a Master Part

By | 2017-12-22T08:21:20+00:00 August 30th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

Have you ever needed to inspect parts in a CMM, without having a master part? Automated CMMs can be a great time saver when inspecting parts on the shop floor. Traditionally, a master part is measured to generate a master data set. The same routine is then automated and used to measure each production part. Each production data set is then compared to the master data set to determine the actual size of the part and whether it is within user defined tolerances. But what if you don’t have a master part available, or one that was closely produced to drawing nominal? This is where the CMM Master can be a great solution. The CMM Master, based on the Renishaw Equator platform, is a portable, automated CMM, calibrated for high production shop floor inspection. In conjunction with the Verisurf software, it is volumetrically error mapped to increase the traditional Renishaw Equator accuracy down to .0005”. Here you see the CMM Master running an automated measurement routine. When it’s done, it automatically generates a date and time stamped report. One thing that makes the CMM Master unique is that a master part is not required in order to perform on the [...]

Simultaneous Synchronized Scanning

By | 2017-12-22T08:35:53+00:00 June 28th, 2017|Categories: 3D Scanning, Tech Tips|0 Comments

This blog post is going to show you how to scan a mid-size part with tiny features. When scanning a model, you're usually faced with the decision of using a scanner that either has a large scan envelope and good resolution, or a scanner that has a small scan envelope with high resolution. But what if you needed the best of both worlds, that is, to capture both a larger part with small fine details? One way to achieve this is to run two scanners simultaneously, and synchronize them to the same turntable. The Geomagic's Capture scanner has an accuracy of about .0035" and is good for scanning mid-size objects. When scanning a model, it's able to pick up the majority of the geometry, but the small fine features get washed out. This is where simultaneous synchronized scanning comes in. You can synchronize Geomagic's Mini-Capture scanner to the same turntable that is aligned to the Capture scanner. The Mini-Capture has a smaller scan envelope, but an impressive accuracy of about .0015." This is what is needed for capturing the fine details on a small part. To run the scans simultaneously, press the Scan button and the turntable moves. Each scanner [...]

Geomagic Design X

By | 2017-12-22T08:39:04+00:00 June 21st, 2017|Categories: 3D Scanning|0 Comments

With Geomagic Design X software you can easily produce a fully featured, editable, native CAD model, directly from a scan. What is Design X? Design X software is a tool that enables you to recognize geometrical features on a scan, utilize them to create CAD features, then transfer that tree of features directly out to the feature tree of your CAD system. Let’s break this process up into three stages: Auto Segment, Feature Extraction, & LiveTransfer to CAD. Auto Segment Auto Segment in Design X allows you to split the polygonal mesh into regions, created by grouping adjacent polygons with similar curvature. As you hover your mouse over each region, Design X displays the geometric shapes that have been identified, like a plane, cylinder, cone, etc. Feature Extraction Once you have all your geometrical regions mapped out, your next step is to extract and create the CAD sketches and features. To do this, start a mesh sketch either directly on a planar region, or a CAD plane, then offset the plane to the location where you want to extract a slice of the polygonal mesh. At this point you will be creating your 2D Sketch entities. You can use that [...]

Reverse Engineering Sheet Metal to a Flat Pattern

By | 2017-05-08T09:31:52+00:00 May 8th, 2017|Categories: 3D Scanning|0 Comments

Today we are going to talk about how to reverse engineer a used sheet metal part back to its original flat pattern. This can be challenging at times, since sheet metal parts tend to bend and distort with normal use. Geomagic Design X can assist you in interrogating the geometry of the part, and reverse engineering it back to the original un-warped shape. After scanning the part, you can import the resulting point cloud into Geomagic Design X and clean up scan file. Next, convert the points to a polygonal mesh, and Auto Segment the mesh. By auto-segmenting the mesh, Design X creates regions made up of polygons that have similar curvature values. Thus, it becomes easy to identify and interrogate geometric shapes. You can then use these regions to create and establish your Datums. At this point, you can start reverse engineering your CAD file by tracing over the mesh profiles, and creating real 2D and 3D geometry. Design X keeps a CAD history tree of everything you’re doing. When you have captured enough information from your polygonal mesh, you can then export your work to your CAD software. In CAD, you can complete your design by converting your [...]
